Very poor performance under Linux

[PhilD]

Not sure if this qualifies as a bug, so I'm posting in a new thread...

Today I tried installing Dom3 on my laptop, and since the OS I use 99% of the time with it is Linux, I first installed on Linux.

What I found out was that the graphics were extremely slow - like 1.4 FPS on the lowest setting. And I'm running up to date Linux drivers from the manufacturer (ATI, I believe - I didn't check, but I seem to remember that).

When I switched to Windows (XP), the game ran perfectly fine and fluid.

Did anyone else notice a performance gap between the OSes? (I still have to check on my home desktop, see if it's similar) With Dom2, I never had the same problem - indeed I almost only played Dom2 under Linux.
